Abstract

This invention is an 'improved AC/DC electric adapter with the large and small plugs'. The main body of the device consists of upper and lower casings; inside the box, there is an electronic converting circuit. In its upper casing, there is an indentation design to hold the large plug; in the large plug, there is a small plug with the rotary pins. The small plug pins can be rotated into the ordinary formation (with the shape of '11') or the two angled formations because there are the following internal designs: two insulating pieces with three guiding holes and push-up pieces (the latter can make the pins mesh with the three guiding holes). Therefore, the small plug pins can be used to draw current from the regular socket or angled pin socket. In addition, its electronic converting circuit can convert the AC into low voltage DC. So, the invention can be used indoors. If we want to use the invention outdoors, we can extend its lighter socket plug outwards from the tube-shaped indentation in the lower casing to draw current from a cigarette lighter socket in an automobile, then this DC current will be converted into lower voltage current to be suitable for the some appliances.
